Patented Nov. 25,v 1930 ROBERT H. HARDIN, OF BAKERSFIELD, CALIFORNIA AIR-COOLING DEVICE Application filed February 15, 1930. 4Serial No. 428,799.

This invention relates to a device primarily designed for the use in reducing the temperature in the rooms of public buildings, hotels,

` schools or the like, by supplying cold lair to 5 therooms.

Another object of the invention is topro-y vide a device of this character which may be effectively employed as a Ventilating system .for supplying pure air to the rooms of buildlngs.

A still further object of the invention is tov provide air tubes through which the air under treatment,is forced, the air tubes being of such construction asI to insure the maximum cooing of the air by the minimum amount of col n With the foregoing and other objects in view, which will'appear astthe description proceeds, the invention resides in combination and arrangement of parts and'in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within'the scope'of what isfclaimed, without departing from the spirit of the invention. Referring to the drawings:

Figure is a longitudinal-sectional view through an air cooling device constructed in accordance with the invention.

Figure-2 is a sectional view taken on line" 2 2 of Figure 1.

Figure 3 is a sectional view taken on line 3-3 of Figure 1.

Referring to the drawin s in detail, the

device comprises a box-like 'ody portion in- L dicated generally b the reference character 5, the body portion beingconstruc'ted of suit- Vable sheet metal material or red clay covered with asbestos or other suitable heat insulating material, such character 6.

The body portion 5, which is in the form ofa tank, is formed with a transverse` passageway extending directly through the body portion, the ends thereof communicating with the atmosphere. 4The bottom of the members in the passageway are closed, as

clearly shown by Figure 1 of the drawings so that water contained in the body portion or belt 10 operates over a suitable as indicated vby the referencei \be withdrawn from the body portion for remain. y Arranged within the passageway and disposed vertically, are a plurality of wide flat hollow members 7 which are arranged in par- 55 allelspaced relation with each other defining transverse passageways, the upper edges of the members 7 'being open and in communiv tank, may enter the hollow --members and cation with the interior'of the body, portion or tank, `so that water contained in the body 30 portion may enter the members 7, to cool them. v u

As shown bythe drawings, the-members 7 are formed with offset end portions 8 to cause the air passing between the members 7 to take 65 an irregular course, retarding the air and insuring the air contacting with both sides'of the members 7 to cool the air.`

The reference character 9 designates a blower housing in which a blower not-shown,

is mounted, the blowerbeing operated rby the beltA 10 loperating over the pulley t1.I This v power pulley not shown. The pipe 12 establishes communication between the blower housing 9 and the `75 spaces or passageways between the members 7 so that air from. the blower housing may be directedI through the passageways or spaces. VAfter the air passes through ,the

vspaces or pasageways between the members it may be supplied to the' rooms of buildings, in any desired manner.

Water and .ice are placed in the body portion 5 so that the cold from the ice will cool the Water which will be transmitted to the members 7 to cool them,

The reference character 13 designates a removable cover for the body portion so that water and ice may be readily placed within u the body portion and the cover placed in position to close thebody porti`on. A spigot such as indicated by the reference character 14 is-mounted on the body portion and extends into the body portion so that ice water may v drinking purposes.

f 1./ In a device of the character described, a body portion for the reception of waterl and ice, said body portion having a' trans- I versely dispose-d passageway, a plurality of hollow members arranged within the passageway, said hollow members having offs'et end portions to cause air `forced between the hollow members to take an irregular path, means for forcing airpbetween the hollow members,

and means for causing the Water in the body portion to enter from the top to the bottom of the hollow members.

2. In a device of the character described, a body portion, a passageway extending through-the body portion, hollow members arranged in parallel spaced relation with each other, positioned in the passageway, said hollow members having angularly disposed end portions, means for forcing air between the hollow members, andmeans for causing water to enter throughthe body portion.

l In testimony that I claim the foregoing as my own, I have hereto affixed my signature.

ROBERT I-I. HARDIN.
